Microsoft says IT admins can re-enable the retired Exchange Web Services (EWS) API in Exchange Online to fix EWS apps that have stopped working. EWS is an API for developing apps that can access Exchange mailbox items (e.g., email messages, meetings, and contacts) from Exchange Online and on-premises Exchange servers. This API is used by various apps, including but not limited to Outlook desktop add-ins, older versions of Outlook for Windows, the Apple Mail / Calendar on macOS, and various other apps. In February, the company announced it will start blocking the EWS API by default on October 1, 2026, but will let IT administrators temporarily maintain access via an app allowlist until the final shutdown on April 1, 2027. However, when EWS is disabled, the apps show errors ranging from alerts that the EWS protocol is unavailable to repeated prompts to enter the username or password.

GitLab has released security patches for a maximum-severity Regular Expression Compiler flaw that can let remote attackers run arbitrary code on vulnerable servers. This security issue is tracked as CVE-2026-110264 and was reported by a security researcher using the 'joaxcar' handle through GitLab's HackerOne bug bounty program. CVE-2026-110264 stems from an integer overflow weakness in GitLab's Regular Expression Compiler, a background engine that parses and validates regular expressions in configuration files. GitLab has fixed the vulnerability in GitLab Community Edition (CE) and Enterprise Edition (EE) versions 19.5.1, 19.4.3, 19.3.6, 19.2.9, 19.1.9, 19.0.10, and 18.11.13, and warned users to patch their instances immediately. "GitLab has remediated an issue that, under certain conditions, could have allowed an unauthenticated user to execute arbitrary code on the GitLab server due to integer overflow when compiling a specially crafted regular expression," the company said.
